You are bidding on (4) NEW VU Meter Lamps (51.02.140) for Revox /  Studer A80 A67 B67 B77 PR99 A700 reel to reel tape machines.  Also works for the pilot light in the a77 machines. 

This is an new and un-used part. 

These are the correct 24 volt bulb as original.  Do not be fooled by folks selling 28 volts bulbs - these may work but the additional heat they generate is not good for Studer machines.

This auction is for FOUR bulbs.
